As we all know. looking for the best Firefox extensions in Official Firefox Add-ons is like searching for the proverbial needle in a haystack.

I am a Firefox extensions addict and I try a lot of extensions every week. You can see my periodic new extensions in the Firefox Extension Picks series that I feature once in every few weeks.

I uninstall the ones that I don’t like or need and the ones that stick around in my browser make it to this list.

History of this list

I put together this list when I wanted to share these wonderful extensions to my friends new to Firefox. As well as this serves as my own reference when I am setting up a new Firefox browser or for some reason restore my own browser from scratch, this is the list I refer to get my Firefox extension fix. And I hope it will be yours too.

What started as a list of a dozen add-ons is now the most visited page in ShanKri-la featuring 65+ awesome Firefox add-ons. I keep it updated as and when I find the best of the best of Firefox extensions.

Firefox Tips

Here are a few tips for a fun Firefox browsing experience

It’s always a good idea to backup your profile, extensions, etc. with FEBE before you try a new extension. Some extensions don’t play well together. (Use FEBE – see below)

If your Firefox seems very slow, it could be because you are using a lot of extensions.

Productivity – Extensions aimed at improving Productivity while you use the web for your work

Fun – When you turn to the web to have some fun.

Blogging – Useful for bloggers. Look at the add-ons and you’ll know what I mean.

Social Media – Not all bloggers use all Social Media s this category zeroes in on just the Social Media extensions.

Web Developer – Aimed at techie’s like myself who either run a website or do some web development.

Starter Pack

If you are just trying out Firefox, here are a few extensions that will introduce you to the power of Firefox.

Adblock Plus– Ever been annoyed by all those ads and banners on the internet that
often take longer to download than everything else on the page? Install Adblock Plus now and get rid of them.

Adblock Filterset.G Updater– This is a companion extension to Adblock or Adblock Plus and should be used in conjunction with it. This extension automatically downloads the latest version of Filterset.G every 4-7 days.

ForecastBar Enhanced – Mod of the popular ForecastFox that shows weather information in your status bar. This one features enhanced animated radar map as well and I love it!

Aimed at the power users who aren’t afraid of getting their hands dirty and who want to squeeze every bit of power from their favorite browser.

CLEO package – CLEO is (Compact Library Extension Oraganizer) an extension that helps you create your own extension package (as a .xpi file) from your favaorite extensions (backed up using FEBE). When you want to move your extensions to another computer or three, just copy the custom xpi package you created and open it. Voila! You have cloned your Firefox extensions..

Firefox Environment Backup Extension (FEBE) – Schedule and automatically back up everything about Firefox.. bookmarks, profiles, saved passwords, form history, etc. No more fear of re-installing Firefox or breaking it with a new extension. You can even upload your backups to your Box.net account.

Foxmarks Bookmarks Synchronizer – Use Firefox on multiple computers? Install this extension, create a Foxmarks account an forget about keeping your bookmarks in sync. Foxmarks will do it for you.

OpenSearchFox – Add any website’s search box to your Firefox search bar by right clicking in the searhch box in a website! It doesn’t appear in the Firefox add-ons site anymore but this link takes you to the download page and it works great even in Forefox 3.0.1.

Menu Editor – TinyMenu mentioned in the next section helps save real estate but it increases the number of clicks to get to your menu option. Menu Editor lets you completely customize your menus. Hide and rearrange options you don’t need making your Firefox menus work for you.

SecureLogin – It uses the Firefox’s built in password manager and disables automatic pre-filling. It highlights the form fields if it detects a saved password and with a customized click or a keyboard shortcut, it fills the username/password as well as signs you in, in one short step. Very useful! I, however, recommend using a more powerful password manager such as Passpack.

Stylish – Stylish is for CSS where Greasemonkey is for Javascript. Completely customize the looks of websites with Stylish scripts. Browse UserStyles.org to find the ones you like. One of the popular example is Re-Designed Gmail Stylish script.

Update Notifier – If you can’t wait to know when a Forefox extension has been updated so you can upgrade it right now. Also, provides a useful ‘Restart Firefox’ option in its menu to restart with one click.

Site Launcher – An experimental add-on thats a must-have for thos who love keyoard shortcuts. Just think Launchy for Firefox. You can launch your favorite sites with just a few hotkeys. Read the full Site Launcher review here.

Usability Add-ons

Aimed at improving browser usability by modifying Firefox chrome or the built-in features.

Back to Top – Back to Top helps navigate long pages. Go to the top or bottom of a page with a single click. Using right clicks and control clicks you can scroll a page or line at a time.

Download Statusbar – Download and view status of downloads in a tidy statusbar. No more annoying download window blocking your browsing experience. A full view as well as a tiny view for screen real estate usage.

Edit Middle – Firefox 3 introduced the Awesomebar. Now whatever you type searches even the middle of the url.

HashColoredTabs+ – Adds a colored favicon square for those sites without a favicon. This helps you identify tab contents based on a distinct visual cue.

FaviconizeTab – If you are in the habit opening a dozn tabs anytime you are browsing, this can be save you some real estate in your tab bar. You can also preset certain to sites to always show just the Favicon and not the name of the site in the tab.

FireGestures – Allows you to execute common commands (like page forward/backward, close tab, new tab) by mouse gestures drawn over the current webpage, without reaching for the toolbar or the keyboard…

It’s All Text! – If you hate the little comment boxes in blogs or little text boxes where you need to type a long reply or complaint, this extension is for you. It adds a little edit button to the box and on clicking will take you to your favorite editor and on saving will transfer the content over to the box in the web page. Very handy.

Smart Bookmarks Bar – Do you customize your menu bar to save screen real estate? Now you can hide your bookmark names in the toolbar and show just the favicon saving a lot of space. On mouse over, you’ll see the name of the bookmark for those without a favicon.

Extensions aimed at improving productivity while you use the web for your work. Supercharge it now!

Social Media Add-ons

Not all bloggers use all Social Media so this category zeroes in on just the Social Media extensions.

Digg Toolbar – For the power Digg.com user. Digg, submit content and get notifications of popular content without ever visiting Digg.com.

Feedly – A fun social startup webpage extension. It integrates with Google Reader, Twitter, Facebook, etc and gives you a magazine style start page. You can even annotate, share stories and leave comments in blogs right from the Feedly page.

Sage RSS Reader – Sage is a lightweight RSS and Atom feed aggregator extension for Mozilla Firefox. It’s got a lot of what you need and not much of what you don’t.

Shareaholic – A catch-all extension for social media sites. Supports multiple web 2.0 sites such as StumbleUpon, Digg, Delicious, Facebook, etc. If you have a social media sharing addiction, this is just for you!

StumbleUpon – StumbleUpon lets you “channelsurf” the best-reviewed sites on the web. It is a collaborative surfing tool for finding and sharing great sites. This helps you find interesting webpages you wouldn’t think to search for. (my StumbleUpon profile)

TwitterFox – One of the earliest Twitter add-ons I used. It’s nice and works well. But, there are a lot of other Twitter add-on options you can choose from.. I prefer using Adobe AIR clients such as Twhirl or TweetDeck for Twitter as they povide more options.

Web Developer Add-ons

Aimed at techie’s like myself who either run a website or do some web development.

Aardvark – Powerful and user-friendly selector utility for selecting elements and doing various actions on them. It can be used for cleaning up a page prior to printing it (by removing and isolating elements), for making the page more readable, and (most appreciated by web developers), for analyzing the structure of a page.

EditCSS – Stylesheet modifier in the Sidebar. Great to save your own custom stylesheet in a browser and view the changes realtime. I prefer Firebug for this but some people might find this handy.

Firebug – A must have. Firebug integrates with Firefox to put a wealth of development tools at your fingertips while you browse. You can edit, debug, and monitor CSS, HTML, and JavaScript live in any web page… (check out FireBug Lite bookmarklet that works in IE & Opera)

FireCookie – A Firebug extension for Firefox that lets you view and manage cookies.

FirePHP – Lets you print to your Firebug console with a PHP function call. You need to have the ‘Net’ panel enabled and also download a PHP library from www.firephp.org.

FlagFox – Just shows the flag of the country the web server is in for the website you are currently viewing.

IE Tab – Switch to IE for ‘those sites’ that work only on Internet Explorer without leaving Firefox. Mark it and it will remember next time you visit those sites.

MeasureIt – Draw out a ruler to measure height or width of any element in a web page. A must have.

Pallette Grabber –

Server Spy – Server Spy indicates what brand of HTTP server (eg. Apache, IIS, etc.) runs on the visited sites. When a tab is selected, the corresponding server name is shown on the right-hand side of the browser’s status…

ShowIP – Show the IP address of the current page in the status bar. It also allows querying custom services by IP (right mouse button) and Hostname (left mouse button), like whois, netcraft. Additionally you can copy the IP address to the clipboard.

Hope you enjoyed this list. Check back later to see new additions. If you found it useful, I’d appreciate it if you could take a moment to share this via your favorite social media site so more people can benefit.

Hey there! I saw your comment on my blog about my list of Firefox extensions and I just wanted to say that I read through your list here and added the Copy Plain Text and AdSense notifier extensions. Very cool stuff!

Joy thanks for taking the time to comment! Obviously, I love using Firefox and experimenting with new add-ons. Hope you found these useful.. also you may want to subscribe to our feed if you’d like to keep up on the periodic Firefox Extensions Picks post I do couple of times a month.

Hey what about Youlicit firefox extension? I think it’s really cool the way it delivers related web sites. Probably a great tool for power users. Check it out, and consider putting it on your list if you like it.

Hi, thanks for the comment! Youlicit sounds like a pretty cool extension. I am installing it right now and will give it a whirl this week. I do a feature post every week and I’ll probably add this in it. Thanks for the heads up! 🙂

Wow.. this is a really useful list man.. I do not have time to try them all yet, but I did try to install the Adsense Notifier, and it works great for me.. save me quite some time (for logging into my Adsense account every hour 😛 ) .. Thanks!

flattering nopes not really i like your blog since i first saw it 6 months back (i think the author is not the same now) i was running stylusouls.com and now its techiesouls. and i can clearly remember you were the only commenter on my blog then and i can never forget this blog seriously i mean it 🙂

Hi, the best firefox screengrab program I think is fireshot – it lets you annotate the screenshots, instantly email, save or upload them etc. Only problem is it doesn’t work with Macs. It’s at screenshot-program.com/fireshot.

Download helper – This great tool will download to your hard drive any video that it finds on the web page. This is quite useful if you want to save and view a video for later replay. http://www.downloadhelper.net/

hey K,
You rock! I’ve just bookmarked this post. I switched to Firefox from IE6 about a month ago and don’t know why I didn’t do it a LONG time ago. Extensions rule! Funny thing is, I just installed Adblock Plus yesterday based on another blogger’s recommendation, then I read this post and see it at the top of your list. Small world! Oh well, enough gushing about Firefox already, eh?
~ Steve, the firefox-loving trade show booths trade show guru

Hey Steve, glad that you liked it! Firefox rocks and as you can probably see that I talk about it a lot! 🙂 Glad you bookmarked this post as I always enter the best ones I find in this post. I do try a lot more extensions that don’t make it here though.

Wow, you know everything firefox-no doubt! I need to start using some of these extensions. I mean I use a lot of wordpress plugins but just haven’t gotten in to the extensions yet.
Thanks for your extensive list I’ll be back to take advantage!
